I want to use XGBOOST instead of Randsom Forest in this workflow i found in KNIME.
I cant execute the metanode : Calculate feature importance.
Is it a problem of output ?
please provide the failing workflow and/or describe clearly what the error is. I do not see any error in the screenshot.
if there is an error then you can find that when you right click an open/expand the metanode

Starting from this workflow. I want to use XGBOOST but i don’t know how to configure math formula in the metanode to obtain the same result.
Thanks for your help/
Attribute statistics(splits and candidates), which are output from random forest node, are used for calculating the feature importance, but XGboost node doesn’t ouput them. So I don’t think this workflow can be used as is with Xgboost. Instead, Global feature importance may help you. Please see the following thread.
I don’t find where we can change the tittle
Example (RF Four Classes) instead of (RF Two Classes)
Dear @Brain ,
In brief, open the component - bar chart - general plot options - title
After executing the component, you can change the configure of the bar chart.
